HINGE.

SPECIFICATION forming part of Letters Patent No. 480,790, dated August16, 1892.

Application filed November 28, 1891. Serial No. 413,390. (No model.)

T0 all whom it may concern:

Be it known that I, THOMAS TANGNEY, a citizen of the United States,residing at South Superior, in the county of Douglas and State ofVisconsin, have invented certain new and useful Improvements in Hinges;and I do hereby declare the following to be a full, clear, andexactdescription of the invention, such as will enable others skilledinitheart to which it appertains to make and use the same. My inventionrelates to hinges, and the object of same is to provide a hinge that issimple and practical in construction and 0peration and one which can becountersunk in the door-jamb or door, so that the door will iit closerthan with the ordinary hinge, and when closed the hinge cannot be seen.I attain said object by a certain construction, combination, andarrangement of parts fully described in this specification andillustrated in the accompanying drawings, in which- Figure 1 is aperspective view of the hinge closed. Fig. '2 is a similar view of thehinge open. Fig. 3 is a horizontal section. Fig. 4 is a detail view ofthe parts detached which compose the hinge. Fig. 5 shows a modification0f my hinge.

Referring to the drawings, the letter A designates the j amb-plate ofthe hinge, which is provided upon the rear side thereof with theprojecting box or hollow casing A. This casing or box when the hinge isapplied to the door is preferably counter-sunk within the door-jamb. Itis well to mention the fact, however, that said casing can becountersunk in the door, gate, rbc., and the hinge equally as welloperated. It will be seen that the ends ct of the jambplate A projectslightly beyond the sides or ends of the box A and that in each of saidprojecting ends there are screw-holes a', through which the screws areplaced, which rigidly secure the same to the door or door-jamb. Anopening a4 is provided in the face end of the casing for a purpose whichwill hereinafter more fully appear. In one of the sides of the boX A ofthe jamb-plate A there is a slot a2. The inner sides of the walls of thecasing leading up to said slot a2 are beveled, so that the end b of thecurved or V-shaped arm B of the plate B is adapted th'ereto and will fittherein, the same working freely in the opening d4. The wall a3 of thecasing A adjacent to the slot a2 is curved inwardly and projectsslightly beyond the side of the casing, so that the same is adapted tofit closely in the inner angular portion b2 of the curved arm B of theplate B, thereby performing the function of a stop and support for saidarm when the hinge is opened to its full extent. The side b of the plateB in front of the point to which the curved arm B is secured is slightlyconcave, so that the same is adapted to work smoothly over the curvedand outwardly-pro jecting wall a3 of the casing A. The plate Bcorresponds in length and width to the jamb-plate A and is likewiseprovided with similar screw-holes b3, whereby the saine may be securedto the door. The end Z9 of the angular or V-shaped arm B is providedwith an orifice b4 and secured in the slot a2 by means of thejournal-rod O, which is journaled through the orifice b4 and hasbearings c c in the sides of the box A of the jambplate A. Such beingthe case, it is apparent that the plates A and B, respectively, arehinged or pivotally secured together, by virtue of which they are heldin their normal positions and enabled to perform their respectivefunctions.

As it is apparent that my invention is very practical and useful inoperation, I deem it useless to further enlarge upon its merits.

1. In a hinge, the jamb-plate A, having the casing A', said casing beingprovided with an inwardly-beveled slot @2in one of the sides thereof,and an inwardly-curved and outwardly-projecting wall a3 adjacent saidslot, in combination with the plate B, having the concaved portion1;,.and the curved or V- shaped arm B', the end b of said arm beingadapted to be journaled in the inwardly-beveled slot a2, whereby whenthe said plate B is swung outwardly the curved portion bzthereof willrest on the outwardly-projecting wall a3 of the casing, substantially asand for the purpose shown and described.

2. In a hinge, the combination, with a plate having upon one sidethereof a curved or V- roo shaped arm, the jamb-plate A, havingthe Intestimony whereof I aflx my signature 1n casing A', said casing beingprovided with an presence of two Witnesses. inwardly-beveled slot a2 inone of the sides thereof, and an inwardly-curved and out- 5Wardly-projecting wall a3 adjacent said slot, Witnesses:

substantially as described, and for the pur- JAMES S. WALLACE, pose setforth. GEO. A. SHEDD.
